I haven't seen anyone mention this improvement, but it's nice to see Tesla is continually improving NOA. As of the 2020.48, I've noticed that NOA no longer automatically defaults to the HOV lane. Prior to this update, the car would always take HOV even if the freeway is wide open at 1:00 AM. Now, NOA will only move over one lane if it detects traffic moving slower than your set speed, otherwise it tracks with the other cars and continues in the same lane.
